Question

an inflatable toy has a volume of 310 mL. when a child takes it aboard an airliner the atmospheric pressure is 0.995 atm. as the airliner climbs,the cabin pressure drops, the toy expands to a volume of 440 mL. what is the air pressure in the airplane

Answer 1

Answer:

P₂ = 0.7 atm.

Explanation:

Given data;

Initial Volume = 310 mL

Initial Pressure = 0.995 atm

Final volume = 440 mL

Final pressure = ?

Solution;

P₁V₁ = P₂V₂

P₂ = P₁V₁/V₂

P₂ =  0.995 atm . 310 mL / 440 mL

P₂ =  308.45 atm. mL /440 mL

P₂ = 0.7 atm.
